What damping devices does Shaoshan 3 locomotive have?
② Depth analysis:
Dear, in order to improve the running stability and riding comfort of Shaoshan 3 locomotive, three kinds of shock absorbers are adopted: spring shock absorber, hydraulic shock absorber and rubber shock absorber:
First of all, the spring damper is the main device of the vibration reduction system of Shaoshan 3 locomotive, which is installed between the bogie and the car body. It uses the elasticity of the spring to absorb the uneven vibration of the road surface, thus playing the role of shock absorption and improving the driving stability.
Secondly, the hydraulic shock absorber, also known as the oil shock absorber, is installed between the bogie and the axle box. It uses the pressure and flow of oil to consume vibration energy and achieve the purpose of vibration reduction. The hydraulic shock absorber can effectively reduce the vibration transmitted from the bogie to the car body, thus reducing the vertical and lateral vibration of the car body and improving the ride comfort.
Thirdly, a rubber shock absorber is installed between the car body and the bogie to reduce noise and vibration by using the high elasticity and damping of rubber material. Rubber shock absorber is characterized by simple structure and good vibration reduction effect, which is especially important for high frequency vibration. It can effectively reduce the noise and vibration at the underframe of the car body, improve the performance of the cab and bring a more comfortable riding environment.
Finally, these three damping devices cooperate with each other and work together, which effectively reduces the vibration and vibration of each frequency band caused by uneven road surface, and greatly improves the running stability, wheel-rail compatibility and ride comfort of Shaoshan No.3 locomotive, which is one of the important reasons why this locomotive is welcomed by railway operators.
③ Suggestions:
Dear, the following are some suggestions for you to buy and use Shaoshan 3 locomotive:
1. When purchasing, you can consider whether the vehicle's damping device is complete and the design is advanced, which is related to the driving stability and ride comfort of the vehicle.
2. Regularly check the service condition of the vibration damping device, and replace the seriously damaged or aged vibration damping elements in time to ensure the vibration damping performance.
3. If you feel great vibration during driving, first check the condition of tires and damping elements, which may be the main cause of vibration.
4. It is suggested to choose brand products to replace the vibration damping device and install it in strict accordance with the locomotive design requirements. Improper installation will affect its vibration reduction effect.
5. Pay attention to its sealing performance when purchasing hydraulic shock absorber to prevent oil leakage from affecting driving safety.
6. Encourage regular inspection of NVH performance of locomotives, and timely repair when problems are found.
